project_overview

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The annotations already establish that this is a safe, idempotent, non-destructive read, so the safety burden is lifted. The description does add one genuinely useful behavioral nuance — that mcp_tools is a live list that may differ from a client's cached list — but says nothing about scoping, error behavior when a project_id is unknown, or cost.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

It is short and front-loaded, with the operation first and the clarifying notes after. The second paragraph is dense but each sentence carries real information, so there is little waste despite the overall terseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return-value documentation is not required. However, for a tool whose purpose is already fuzzy and whose siblings include list_projects, the definition does not supply enough context to confidently select it or predict the scope of the 'overview'.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the single project_id parameter is left unannotated. The name is largely self-evident, so an agent can infer its meaning, but the description does no work to explain identifier format, whether it accepts slugs or IDs, or what happens if it is omitted.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names an action (read the registry, locate indices, report Discussion/Freeze permissions) but the resource is described obliquely — 'the registry' and 'indices' are never defined, and the tool name (project_overview) is only loosely reflected. It also gives nothing to distinguish it from the sibling list_projects, which plausibly returns overlapping project data.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no statement of when to call this tool, when not to, or how it relates to alternatives. With siblings like list_projects and refresh_projects in the same namespace, an agent has to guess which one produces the overview it wants.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
